So I’ve built a few repro kit Champs as well as a few clone units, and I’ve come to the conclusion that a ‘stock’ 5F1 when built to spec is almost lame! Granted it’s an iconic amp, but it truly lacks luster and is almost anemic by comparison to other modern day amps. I have a couple Epiphone Valve Junior Amps that scream circles around my Champs, any I recently was blown away by my friends Univalve amp. So in trying to narrow down my two biggest complaints about my stock Champ units, it boils down to simply being too ‘dark’ and too compressed. I’m wondering what others may think about theses comments, but also if anyone knows any common mods that might address either of these symptoms?
